To solve the equation 11x + 12 = 8x - 9, you want to isolate the variable x on one side of the equation. You can do this by moving the x-terms to one side and the constant terms to the other side.
11x + 12 = 8x - 9
First, subtract 8x from both sides to eliminate the x-term on the right side of the equation:
11x + 12 - 8x = 8x - 9 - 8x
3x + 12 = -9
Next, subtract 12 from both sides to eliminate the constant term on the left side of the equation:
3x + 12 - 12 = -9 - 12
3x = -21
Finally, divide both sides by 3 to solve for x:
3x/3 = -21/3
x = -7
Therefore, the solution to the equation is x = -7.
Solve the equation.
11x+12=8x-9
